UNITED STATES PATENT JOACHIM EGGERT, OF BURG, FEMERN, GERMANY.

INVALID-BED.

SPECIFICATION forming part of Letters Patent No. 513,310, dated January 23, 1894.

Application led August 4, 1892. Serial No. 442,137. (No model.) Patented in Germany April 10, 1892, No. 67,681, and in England June 25, 1892, No. 11,905.

To all whom it may concern:

Be it known that I, JOACHIM EGGERT, of Burg, Island of Femern, Prussia, Germany, have invented a new and useful Improvement in Invalid-Beds, (patented in Germany April 10, 1892, No. 67,681, and in England June 25, 1892, No. ll,905,) of which the following is a full, clear, and exact description.

The object of the invention is to provide a bed so constructed that `a bed pan may be properly placed therein without any inconven- 1ence to the patient or requiring the latter to be lifted.

The invention consists in the novel features hereinafter particularly described and defined in the claims.

Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures. v

Figure l is a longitudinal sectional elevation showing the bed in its normal or closed position. Fig. 2 is a similar view showing the bed open for the proper placing of a bed pan. Fig. 3 is a plan view of the bed closed. Figli is a transverse sectional elevation, the section being taken on line 4 4, Fig. 2; and Fig. 5 is alongitudinal sectional elevation illustrating a moditied form.

The bedstead may be of any approved form in so far as relates to the head and foot boards and side rails. At the bottom of the bedstead is a mattresso, which extends longitudinally to about the center of the bedstead, forming the lower half of the bed.

Referring especially to Figs. l to 4, a transverse board or strip q, and a block lc which also ranges transversely serve to securely clamp and hold the end of a web t, which passes over a transverse roller w carried by aslide s, and normally occupyinga position close to the end of the mattress a. From the roller w the web t, which may be of any suitable material, returns to and passes around a second roller o, carried by the slide s, and is secured to a transverse bar d, the latter being in turn secured to the side rails of the bedstead, by brackets d. The slide s is formed at the end toward the foot of the bed with a ledge a for supporting a bed pan, is provided with rollers r that run on track rails Zon the side rails of the bedstead, and is provided with racksy on the under side into which mesh the pinions z, on a handled shaft R. Pendent arms g also project from the slide s asa means of moving it. Between the head of the bed and the roller fw, the web t is supported by the transverse boards or slats b which are supported on brackets c, and the web is further supported by the transverse rods ee, which range at each side of the slats b.

NVith this construction when it is desired to use a bed pan, the slide s is moved in the direction of the head board from the position shown in Fig. l to that shown in Fig. 2, either by turning the handled shaft R in the direction ofthe arrow Fig. 1, or by means of arms g, thereby providing an opening as in Fig. 2, about centrally of the bed, below which is the ledge u for supporting the bed pan. It will be seen that the web is maintained taut at all times and the patient has substantial support Without changing the natural position.

The advantages and convenience of the bed constructed as described, are especially marked in the case of very heavy patients.

In the form shown in Fig. 5 the slide s is alone employed to-torm a closure of the opening in the bed. Thus, the rollers r', of the slide run on inclined tracks Z. The slide in this form moves in an inclined direction, is provided with pusher arms g from which braces i extend to the under side-of the slide, and is further provided with a ledge u', and

ythe handled operating shaft R having pinions z for meshing with the rack of the slide, as in the construction previously described.

At the head ofthe bed, a mattress m is provided, and the space between the mattresses m anda is partially closed bya water cushion h on a suitable support k', and partially by the upper end of the slide s. In order to prevent the water cushion h or the bed-clothes from being caught between the support la and the slide, transverse rods o are provided. The bed-clothes, that is, the sheets and the like, on which the patient lies, are or may bedivided transversely to fall at the opening when the movable closure is moved from beneath the patient.
